It has been reported that the phosphorylated form of histone variant H2AX (gammaH2AX) plays an important role in the recruitment of DNA repair and checkpoint proteins to sites of DNA damage, particularly at double strand breaks (DSBs). Using gammaH2AX foci formation as an indicator for DNA damage, several chemicals/stress factors were chosen to assess their(More)
The multifunctional E4F1 protein is a cellular target of the E1A adenoviral oncoprotein. Interaction between E4F1 and the hepatitis B virus (HBV) protein HBx has been demonstrated in vitro. In this study, RNA interference has been used to downregulate E4F1 in the hepatocellular carcinoma (HCC) cell line HepG2 (HBV negative) and its derivative, HBV(More)
